Supposedly my husband is an ISTP and I'm an INFP. He seems to like me just fine, although we have had problems. We sometimes talk at each other, because he wants to talk about skateboarding and I want to talk about some cool idea I've discovered and we both have a hard time understanding or paying attention to what the other is saying. There are few movies we can watch together. But we both like concerts. We both like to drink and to eat good food. We both enjoy travel. We both love our kids. I think the key is to have others with whom you can totally INFP-out or totally ISTP-out. Don't expect your significant other to fulfill all your needs- good advice for anyone of any type, point in fact.
